Any progress on pixel art scaling algorithms?

Unless someone volunteers to add it to the library, no.

The -magnify option implements pixel art scaling.

Hmm seems to work well
Code: Select all
convert -size 8x8 pattern:CrossHatch30 -magnify -magnify -magnify show:
compare to direct scaling...
Code: Select all
convert -size 8x8 pattern:CrossHatch30 -scale 800% show:
A little wonky near the edges, but then that should be expected, unless more appropriate
-virtual-pixel tile is used for this specific image
Code: Select all
convert -size 8x8 pattern:CrossHatch30 -virtual-pixel tile -magnify -magnify -magnify show:
Could the scaling method (even just a reference link to the method used) be added to the web page...

Addendum... updated IM Examples (when the update appears online), though I do not know what algorithm was used.

I believe it is scale_2x. See
